A steel structure equipment based on the principle of electrochemical corrosion

Abstract

The invention relates to the technical field of anti-corrosion technology for steel structures in seawater, and discloses a steel structure equipment based on the principle of electrochemical corrosion, including a cover body, the inner side walls of the cover body are fixedly connected with displacement grooves, and the displacement grooves An elastic rod is movably connected inside, and the other end of the elastic rod is movably connected with a roller, and a waterproof rope is wound on the surface of the roller, and the other end of the waterproof rope is movably connected with a winding post, and the lower end of the winding post is movably connected with a telescopic rod, The surface of the telescopic rod is movably connected with a spring, and the other end of the spring is movably connected with a derusting wheel. When the seawater is upwelling, it will push the cover to move upward, and the cover will slide upward on the surface of the steel member, and the arc knife will move in the vertical direction. In addition, affected by the fluidity of seawater, the arc knife will also move in the horizontal direction. Therefore, where the steel member is in contact with the arc knife, the sundries and rust on the surface will be removed, thus achieving the effect of self-rust removal by using the undulating motion of the waves.

[0002] Steel structure is a structure composed of steel materials. It is one of the main types of building structures. It is light in weight and easy to construct. It is widely used in large factories, venues, super high-rises and other fields. With the development of my country's ocean engineering , some bridges or marine equipment also use steel structures, but steel structures contain a lot of carbon and iron, and are easily corroded when soaked in seawater for a long time. The existing technology uses sacrificial anode cathodic protection to slow down the corrosion rate of steel structures

[0003] Although this method is relatively mature, due to the large size of the steel structure, the traditional cathodic protection method can only protect a certain section of the steel component. If you want to protect the entire steel structure, you need a large number of zinc columns, which wastes materials and increases the number of cathodes. Difficulty in implementing the protection method; in addition, the steel structure has been soaked in seawater for a long time, and corrosive substances will adhere to the surface, which will accelerate the corrosion of steel components. However, the existing technology can only use artificial diving to clean it without corresponding treatment. Equipment, so a steel structure equipment based on the principle of electrochemical corrosion came into being
